## Water at the Antarctica usually exits as ice, making it

Water at the Antarctica usually exits as ice, making it very difficult to use the water or conduct experiment requiring the water to be in liquid state. A coffee addicted physicist stationed at a research base requires about 0.8 kg of ice for his coffee on the hour.

a. How much heat is required to convert 0.8 kg of ice at —35 °C into steam at 100°C?

b. Plot the temperature – energy graph for the processes in (a).

c. The surface tension of water was determined in a laboratory by using the drop weight method. 100 drops were released from a burette the inner diameter of whose opening is 1.8 mm. The mass of the droplets was 3.78 g.

i. Determine the surface tension of the water and, comparing it with the tabulated value,

ii. Calculate the relative error of the measurement.

## For Business versus Engineering majors conduct a full,

For Business versus Engineering majors conduct a full, two-sample hypothesis test using the p value method at the 0.01% significance level (assume the variances are not equal). Claim: the average ’30-Year ROI’ for Business majors is less than for Engineering Majors.

a. Will one of the two majors cost more than the other according to the average cost calculated in Week 2 with the sample data? If so, which one?

b. Does the hypothesis tests support that one of the two majors costs more than another? If so, which one costs more?

c. Why did we need the hypothesis test if Week 2 showed us which school from the sample cost more?

d. According to these results, what would you tell our student who is choosing between majors if he/she asked, “What is it going to cost to attend a business/engineering school?”

b) Identify 2 other aspects should they consider that are not reflected in the ratios.

c) What type of mortgage would you recommend for them based on the options provided and why?

## Each group has been given a process narrative related to

Each group has been given a process narrative related to the Sales/Collection or Acquisition/Payables cycle at SP Manufacturing. Your assignment is to document the process narrative in flowcharts. Each narrative details 2 processes; each of which requires its own separate and distinct process flowchart (i.e. you will complete 2 flowcharts). Based on your understanding of the business cycle, you will create a summary slide for each flowchart summarizing the components of the AIS described within the process. Specifically, you will detail the inputs, outputs, internal controls, storage, and processes (i.e. which steps the narratives relate to for the Sales/Collection or Acquisition/Payments cycle) for each flowchart. While you are not documenting the entire process (i.e. all of the generalized steps associated with the cycle), each narrative contains a gap. You are to identify which step is missing and, in a separate slide, detail the risks of not performing that step and what processes should be implemented by the company to address the gap. For example, you may have been given steps 5 and 7 of the Sales/Collection process – meaning that step 6 is missing. Outlook 2 flowcharts – 2 AIS summary slides (one for each flowchart) – A slide (or 2) detailing the missing step, risks associated with not performing that step, and related processes the company could implement to address criteria Flowcharts should follow the general rules outlined in Chapter 6: – The process should flow from left to right and top to bottom – Each flowchart should only have 1 starting point – Groups should appropriately map process narrative elements to symbols – Each flowchart should have a title – Each process box should be numbered – Clean formatting (evenly sized and spaced symbols, white space, spelling, etc.) Sales/Collections Process Narrative Customer purchase orders (POs) are received via email only. Each morning, the Customer Sales Representative will review new orders within Outlook and manually enter the product information (including quantity and price) within the JDE database. Once populated, an independent CSR (not the individual who input the order information initially) will review the order for completeness and accuracy – comparing the input pricing to the Master Price List and the product information (including quantity) to the customer PO. If approved, the order is released. If discrepancies are noted, the order is returned to the orginator (initial CSR) who will update the order as needed until approved by the reviewing (independent) CSR. Once an order is released in JDE, a sales order is sent to the customer. Based on the approved order, JDE will automatically generate a picking list and notify the Warehouse department. Using the picking list, a warehouse employee will fulfill the order – selecting the required items from the warehouse and loading. If there are items that are unavailable, the warehouse employee will update within JDE to note which items cannot be fulfilled at this time. All amended picking lists require review and approval by a Warehouse Manager. Once finalized, the picking list and related products are sent to the Shipping department. Answer Skip

## Many signaling molecules exist in very miniscule

Many signaling molecules exist in very miniscule concentrations within the body, yet trigger very large responses within the cell. How does this occur?

A. Signal recognition induces the release of ATP which gives the cell more energy to produce a large response.

B. Signal recognition induces crosstalk to other signal receptor proteins, all of which then respond to the initial signal.

C. Signal recognition induces mitosis by the cell, and all of the daughter cells respond to the initial signal.

D. Signal recognition induces the release of secondary messengers which amplifies the signal within the cell.

## Tonya Stephani is the front ofﬁce manager/RM at the

Tonya Stephani is the front ofﬁce manager/RM at the 200-room Hilton Garden hotel. Tonight, she has 100 stay-over rooms and 100 arrivals. Based on her own forecasts, she anticipates 10 no-shows tonight. The average rate to be paid by each arriving guest is \$199.99. Tonya has a signed agreement with the local Sheraton hotel that states each property is willing (subject to blackout dates) to accept the other’s walks at the rate of \$99.00 per night. Tonight, the Sheraton has available rooms and has agreed to take up to ten walked guests. The cost of transporting guests to the Sheraton and back, as well as other walk related costs incurred by the Hilton, average \$15.00 per room. Assume Tonya decides to overbook by ten rooms.

• Excluding any potential no-show billings, how much extra room revenue will be gained from overbooking if Tonya indeed experiences ten no-shows but overbooks by ten rooms and thus achieves a 100 percent occupancy?
• How much extra cost will the hotel incur if it sells out, but ultimately walks 1 guest?
• How much extra cost will the hotel incur if it sells out, but ultimately walks 10 guests?
• If the hotel walks 10 guests, what would be the net revenue (i.e., difference between the extra room revenue from overbooking and the associated costs of walking those 10 guests)?
• In addition to added room revenue and potential costs, what are at least three other factors Tonya should consider as she makes this overbook/no-overbook decision for her hotel?

## Use the chromosome bead models to model meiosis with one,

Use the chromosome bead models to model meiosis with one, two, or three pairs of homologous chromosomes. By doing this exercise you should be able to determine all the different combinations of chromosomes that are possible in gametes due to the independent assortment of homologous pairs. Diagram all possible arrangements in the circles provided using red for maternal chromosomes and yellow
for paternal chromosomes.
You will disregard crossing over between homologous chromosomes for this exercise.
A cell with one pair of homologous chromosomes (n = 1)
Assemble two duplicated chromosomes, one red and one yellow, with 10 beads on each end of the centromere. By modeling meiosis, determine all possible combinations of chromosomes in gametes when n = 1 assuming there is no crossing over, and diagram each combination in the circles below using different colors for maternal and paternal chromosomes.

## Design a “disk spinning” animation circuit for a CD

Design a “disk spinning” animation circuit for a CD player. The input to the circuit will be a 3-bit binary number A 1 A 2 A 3 provided by another circuit. It will count from 0 to 7 in binary, and then it will repeat. (You will learn to design such counters in Unit 12.) The animation will appear on the top four lights of the LED display of Figure 8-15, i.e., on X 1 , X 2 , X 7 , and X 6 , going clockwise. The animation should consist of a blank spot on a disk spinning around once, beginning with X 1 . Then, the entire disk should blink on and off twice. The pattern is shown.

Design your circuit using only two-, three-, and four-input NOR gates and inverters. Try to minimize the number of gates required. Any solution which uses 11 or fewer gates (not counting the four inverters for the inputs) is acceptable.
